Vortex rifle

The Union Aerospace Tactical Division V-ORT.X Rifle, or vortex rifle, is a new energy weapon which appears in the multiplayer and SnapMap modes of the  Doom. Referred to in passing as a "laser sniper rifle," it can be focused to deliver more powerful shots at a longer range. The focusing process is done in the alternate fire mode, in which the wielder makes use of vortex rifle's optical scope to charge the weapon's shots. However, a distinctive laser sight is produced during the charging process that can reveal the user's location.

"A precision long-range energy weapon with a magnified optic."

Easter egg
When viewed in the multiplayer customization menu, the butt end of the weapon's stock can be seen to have some text written on it, as if with a permanent marker: "Capt K. Cloud PLT 46-849". This refers to long-time id Software artist and producer Kevin Cloud.
